Is it worth repairing a 20-year-old eavestrough or should I just replace it in Ottawa?

A 20-year-old eavestrough system in Ottawa is right at the decision point where replacement often makes more financial sense than ongoing repairs. Most aluminum eavestroughs in our climate last 20 to 30 years, while you're now entering the period where multiple components typically start failing simultaneously.

The key factors for your decision depend on the current condition and material of your existing system. If you have aluminum eavestroughs with isolated problems like a few loose hangers, minor leaks at one or two seams, or a single damaged section from ice or ladder damage, targeted repairs costing $200 to $500 can extend the system's life by 5 to 10 years. However, if you're seeing multiple issues like widespread sagging, numerous leaky joints, rust stains on aluminum (indicating fastener corrosion), or sections pulling away from the fascia, replacement becomes the smarter investment.

Ottawa's extreme climate accelerates eavestrough aging in specific ways that make 20-year-old systems particularly vulnerable. Our 65-degree annual temperature swing causes constant expansion and contraction that loosens hangers and opens seams over time. The 50-plus freeze-thaw cycles each winter stress every joint and mounting point. Ice loading from our heavy, wet snow can bend or crack sections that have lost structural integrity after two decades of thermal cycling. If your eavestroughs have survived Ottawa's harsh conditions for 20 years, they've done their job well, but the remaining components are likely nearing their service life limits.

Consider replacement if you're planning other exterior work like roofing, siding, or soffit and fascia updates within the next few years. Coordinating these projects saves money on scaffolding and labour mobilization. Also factor in the improved performance of modern eavestrough systems. Today's seamless aluminum with properly spaced hidden hangers and integrated gutter guards significantly outperforms systems installed in 2004.

From a cost perspective, extensive repairs on a 20-year-old system rarely make sense in Ottawa's market. If repair estimates exceed $800 to $1,200, you're approaching 40 to 50 percent of replacement cost for a new seamless aluminum system. A complete replacement on a typical Ottawa home runs $1,500 to $3,000 and gives you a fresh 15 to 25 year service life with warranty coverage. Multiple small repairs over the next few years often total more than upfront replacement costs.

For an accurate assessment of your specific situation, have an experienced contractor evaluate the overall system condition, hanger integrity, and fascia board health.
